Describe the similarities and differences between the mechanism of import into the mitochondrial matrix and the chloroplast stroma.
Step by step
Solved in 2 steps
- 1. a) Describe the Q cycle in detail providing the names of electron acceptors and donors. b) How is ATP synthesized by the FOF1 Complex in the mitochondrial membrane?Explain the functions of mitochondrial matrix processing peptidase (MP) and chloroplast stromal processing peptidase (SPP).Explain how a gradient of protons is established across the inner mitochondrial membrane during chemiosmosis
- Explain why an intact, impermeable mitochondrial membrane is essential forATP synthesis.During the FADH2 electron transport chain, the protons are pumped from the mitochondrial matrix to the intermembrane space through complexes CoQ/III, and IV the protons are pumped from the mitochondrial matrix to the intermembrane space through complexes I, CoQ/III, and IV the protons are pumped from the mitochondrial matrix to the intermembrane space through complexes I, CoQ/II, and IV the protons are pumped from the mitochondrial matrix to the outer mitochondrial membrane through complexes I, III, and IVMitochondrial outer membrane permeabilization (MOMP) includes: Question 10 options: a) mitochondrial outer membranes are disrupted. b) caspases activation in either intrinsic or extrinsic pathway. c) cytochrome c release. d) All of the above. e) Only (a) and (c)
- In the presence of oxygen, the mitochondrion in yeast is used for aerobic respiration,however, under anaerobic conditions,the yeast mitochondria have been found to have other function. Identify and briefly discuss four of these functionsExplain in your own words the transport of four protons out of the mitochondrial matrix via the Q cycle.How are proteins normally transported into the mitochondrial matrix, if they were originally synthesized on ribosomes present in the cytosol (not on the rough endoplasmic reticulum)? they are packaged into vesicles with v-SNARES for fusion with their target organelles they can pass freely through large pores in the inner mitochondrial membrane they are secreted by the golgi, captured by receptors, and absorbed by endosomes they must pass through the nuclear envelope by means of nuclear pores they are unfolded in the translocation channel, then refolded by chaperones
- propose a mechanism that could allow pyruvate to cross the mitochondrial memebranes to enter the mitochondrial matrixDefine chemiosmosis and explain how a gradient of protons is established across the inner mitochondrial membrane.Explain how Ca2+, NOS/RNS and mitochondrial membrane transfer problems are inter-related and how/why this kills cells.
